Description

Technical Field

[0001] This utility model relates to the field of footwear design technology, and more specifically, to a midsole structure for athletic shoes designed specifically for women. Furthermore, it also relates to an athletic shoe incorporating the aforementioned midsole structure designed specifically for women. Background Technology

[0002] In existing technology, the midsole 01 of athletic shoes, as a crucial component of footwear, directly impacts the wearer's comfort, support, and athletic performance. Currently, most athletic shoe midsole 01 designs on the market are based on male weight and gait characteristics, utilizing foam materials and adjusting the rebound force F and cushioning through the density and size of the foam particles 02. For example, as... Figure 1 As shown, the gaps between the foam particles 02 in the midsole 01 of common sports shoes are typically 0.5mm-1mm. The foam particles 02 have a relatively high density, making them suitable for male users weighing between 60kg and 90kg. This design provides moderate rebound force F and stability under high pressure. Traditional midsoles 01 generate rebound force F under different gravitational forces G, such as... Figure 2 As shown.

[0003] However, since women typically weigh between 45 and 70 kilograms and have lighter steps, the traditional 01 midsole design, with its excessively high particle density and insufficient deformation capacity, struggles to provide a rebound and cushioning experience that matches a woman's weight and gait. Specifically, the existing 01 midsole is too stiff, requiring female users to "compress" the sole to accommodate their stride, resulting in poor initial comfort for female wearers. Furthermore, the rebound curve is not optimized for women, potentially increasing pressure on the ankles and knees during prolonged wear.

[0004] In conclusion, how to provide a midsole structure specifically designed for women to improve rebound sensitivity and comfort, and meet women's needs in sports and daily life scenarios, is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a midsole structure for sports shoes designed specifically for women. This midsole structure helps to improve the rebound sensitivity and comfort of sports shoes, meeting the needs of women in sports and daily life scenarios.

[0006] Another objective of this invention is to provide a sports shoe that includes the above-mentioned midsole structure specifically designed for women.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A midsole structure for athletic shoes designed specifically for women includes a midsole body, wherein the midsole body is a foam material component, the gap range of the foam particles in the foam material component is 1.2mm-1.5mm, and the rebound curve of the midsole body is adapted to women with a weight range of 45 kg-70 kg.

[0009] In one embodiment, the foamed material comprises ethylene-vinyl acetate copolymer or thermoplastic polyurethane.

[0010] In one embodiment, the thickness of the midsole body ranges from 10mm to 20mm.

[0011] In one embodiment, the surface of the midsole body is provided with ventilation holes.

[0012] An athletic shoe comprising the midsole structure of an athletic shoe designed specifically for women as described in any of the preceding claims.

[0013] In one embodiment, an outsole patch is also included that adheres to the bottom of the midsole body of the midsole structure of the athletic shoe designed specifically for women.

[0014] In one embodiment, the outsole patch is attached to the bottom of the midsole body using adhesive.

[0015] In one embodiment, the bottom of the outsole patch has anti-slip texture.

[0016] When using the midsole structure of athletic shoes designed specifically for women provided by this utility model, the main body of the midsole is made of foam material. The porosity of the foam particles ranges from 1.2mm to 1.5mm, resulting in a lower particle density than that of traditional men's midsoles. This allows the rebound curve of the midsole to be adapted to women weighing between 45kg and 70kg, ensuring enhanced rebound and support within this weight range. The midsole structure designed specifically for women, by adjusting the porosity and density of the foam particles, enhances the midsole's deformability, allowing it to conform to a woman's gait from the first wear, eliminating the need for an adaptation period. Furthermore, this device optimizes the rebound curve of the midsole structure to absorb foot pressure, reducing the burden on the ankles and knees, better meeting women's physiological needs, and achieving a more sensitive rebound effect and customized softness and cushioning comfort.

[0017] In summary, the midsole structure of the sports shoe designed specifically for women provided by this utility model is a midsole structure designed specifically for women, which helps to improve the rebound sensitivity and comfort of sports shoes and meet the needs of women in sports and daily life scenarios.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] The core of this invention is to provide a midsole structure specifically designed for women's athletic shoes. This midsole structure helps improve the rebound sensitivity and comfort of athletic shoes, meeting the needs of women in sports and daily life. Another core aspect of this invention is to provide an athletic shoe that includes the aforementioned midsole structure specifically designed for women.

[0036] This specific embodiment provides a midsole structure for athletic shoes designed specifically for women, including a midsole body 1, which is made of foam material. The gap range of the foam particles 2 in the foam material is 1.2mm-1.5mm, and the rebound curve of the midsole body 1 is suitable for women with a weight range of 45 kg-70 kg.

[0037] It should be noted that the gap range of the foam particles 2 in the midsole body 1 of this application is 1.2mm-1.5mm, which is lower than the particle density range of traditional men's midsole designs (which is 0.5mm-1mm). This makes the gap of the foam particles 2 in the midsole body 1 about 30% larger than that of the foam particles 2 in traditional midsoles. The smaller the gap of the foam particles 2, the smaller the rebound force F, and the larger the gap of the foam particles 2, the greater the rebound force F.

[0038] like Figures 5-7 As shown, the rebound curve of the midsole body 1 in this application is adapted to women's weight range of 45 kg to 70 kg, ensuring that the midsole body 1 can provide enhanced rebound force F and support (to support the wearer's weight G) within this weight range, which helps to improve the deformation ability of the midsole body 1 and optimize the wearer's initial wearing comfort. In actual use, the shape, structure, material, and foam particle pores of the midsole body 1 can be determined according to the actual situation and needs.

[0039] When using the midsole structure of athletic shoes designed specifically for women provided by this utility model, the midsole body 1 is made of foam material, and the gap range of the foam particles 2 is 1.2mm-1.5mm. This makes the density of the foam particles 2 lower than that of traditional men's midsoles, allowing the rebound curve of the midsole body 1 to be adapted to women weighing between 45kg and 70kg, ensuring that the midsole body 1 provides enhanced rebound force F and support within this weight range. The midsole structure of athletic shoes designed specifically for women, by adjusting the gap size and density of the foam particles 2, enhances the midsole's deformation capacity, allowing it to conform to a woman's gait from the first wear, without requiring an adaptation period. Furthermore, this device optimizes the rebound curve of the midsole structure to absorb stride pressure, reducing the burden on the ankles and knees, better meeting women's physiological needs, and achieving a more sensitive rebound effect and customized softness and cushioning comfort.

[0040] In summary, the midsole structure of the sports shoe designed specifically for women provided by this utility model is a midsole structure designed specifically for women, which helps to improve the rebound sensitivity and comfort of sports shoes and meet the needs of women in sports and daily life scenarios.

[0041] In one embodiment, the foamed material comprises ethylene-vinyl acetate copolymer or thermoplastic polyurethane.

[0042] It should be noted that EVA (Ethylene-Vinyl Acetate) is a polymer material widely used in industrial, consumer goods, and medical fields. EVA foam materials have advantages such as being lightweight and having good cushioning properties, making them a mainstream material for sports shoe midsoles. Moreover, the elasticity of low-VA-content EVA foam materials is similar to that of PE (Polyethylene), while the elasticity of high-VA-content EVA foam materials is close to that of rubber. Therefore, the VA content of EVA foam materials can be determined according to actual conditions and needs during practical applications.

[0043] It should also be noted that TPU (Thermoplastic Polyurethane) is a high-performance polymer material that combines the elasticity of rubber with the processing properties of plastics, and is widely used in industrial, medical, and consumer goods fields. TPU has a wide range of elastic moduli, from a few MPa to thousands of MPa, and also possesses excellent abrasion resistance, approximately 3 to 5 times that of natural rubber. Using TPU foam material to make the midsole body 1 can effectively improve the elasticity, abrasion resistance, impact resistance, and anti-slip effect of the shoe sole. Operators can choose ethylene-vinyl acetate copolymer or thermoplastic polyurethane to make the midsole structure of the sports shoes designed specifically for women in this application. The foaming process forms uniformly distributed foam particles 2, ensuring that the porosity of the foam particles 2 in the foam material component is within the range of 1.2mm-1.5mm.

[0044] In one embodiment, the thickness of the midsole body 1 ranges from 10mm to 20mm. During use, the thickness of the midsole body 1 can be adjusted and determined according to the purpose of the footwear (such as running or commuting).

[0045] In one embodiment, such as Figure 10 As shown, the surface of the midsole body 1 is provided with ventilation holes 3 to further improve the wearer's comfort.

[0046] To further illustrate the midsole structure of the sports shoe designed specifically for women provided by this utility model, the following examples will be given.

[0047] Example 1: Rebound Structure of Running Shoe Midsole

[0048] This means that the midsole structure of women's athletic shoes designed in this application can be applied to running shoes. The midsole body 1 can be made of EVA foam material, with a thickness of 15mm. The porosity range of the foam particles 2 in the midsole body 1 is set to 1.2-1.5mm, the average porosity of the midsole body 1 is set to 1.35mm, and the particle density of the foam particles 2 is 0.15g / cm³. 3 (Its particle density is 0.20 g / cm³ lower than that of traditional midsoles) 3 The particle distribution is adjusted through a foaming process to ensure uniformity.

[0049] Tests show that, within a weight range of 45 kg to 70 kg, the rebound rate of the midsole body 1 of this application is approximately 20% higher than that of traditional midsoles. The initial deformation of the midsole body 1 of this application is 15% higher than that of traditional midsoles, providing a more natural stride feedback. Furthermore, 2 mm diameter ventilation holes 3 can be provided on the surface of the midsole body 1 to improve the ventilation of the running shoe.

[0050] Example 2: Midsole Rebound Structure for Commuter Shoes

[0051] This means that the midsole structure of the women's athletic shoes designed in this application can be applied to commuter shoes. The midsole body 1 can be made of TPU foam material, with a thickness of 12mm. The porosity range of the foam particles 2 in the midsole body 1 is set to 1.2-1.5mm, the average porosity of the midsole body 1 is set to 1.4mm, and the particle density of the foam particles 2 is 0.14g / cm³. 3 (Its particle density is 0.20 g / cm³ lower than that of traditional midsoles) 3 The particle distribution is adjusted through a foaming process to ensure uniformity.

[0052] Compared with traditional midsoles, the rebound structure of the commuter shoe in this application has a rebound time of 0.1 seconds shorter under 50 kg pressure. Wearers report a significant improvement in comfort when wearing it for the first time, and a reduction of about 25% in foot fatigue after walking 8,000 steps a day.

[0053] The midsole structure of this application, designed specifically for women's athletic shoes, increases the particle gap of the foam particles 2 to 1.2-1.5mm, enabling the midsole body 1 to provide stronger rebound force F within the weight range of women (45 kg-70 kg). Its tested rebound rate is as high as 65%, while the tested rebound rate of traditional midsoles is about 50%. Moreover, the initial deformation capability of this structure is enhanced, resulting in a soft feel and good cushioning, making it suitable for daily commuting and light exercise. It also increases the pressure absorption rate of the sole by about 10%, helping to reduce the burden on the wearer's joints and adapting to the light gait of women.

[0054] In addition to the above-mentioned midsole structure designed specifically for women, this utility model also provides a sports shoe that includes the midsole structure designed specifically for women disclosed in the above embodiments. For the structure of other parts of the sports shoe, please refer to the prior art, which will not be described in detail here.

[0055] In one embodiment, such as Figure 3 As shown, it also includes an outsole patch 4 that is attached to the bottom of the midsole body 1 of the midsole structure of the athletic shoe designed for women. The outsole patch 4 can have anti-abrasion and anti-slip effects.

[0056] In one embodiment, the outsole patch 4 is attached to the bottom of the midsole body 1 with adhesive. When the outsole patch 4 is worn, it can be removed and a new outsole patch 4 can be reattached or fixed to the bottom of the midsole body 1 with rivets to improve the performance and service life of the athletic shoe.

[0057] In one embodiment, such as Figure 4As shown, the bottom of the outsole patch 4 is provided with anti-slip texture 5 to improve the anti-slip effect of the sports shoe.
